Talk:6264 static RAM

More pinouts for different sizes of 62* SRAM's

Some extra pinouts for SRAMs: 62256 is identical except for the !CS2 input and NC becoming address lines. This is to make address expansion of a board design almost trivial using inverters as half of an address decoder (other half is !CS input).

CY62256 SRAM (28 pins, 1-14,28-15) Note that the Ax and Dx line order doesn't really matter.
